LAMP-CHIMNEY eoann Specification of Letters latent.

Application filed March 19, 1919. Serial No. 283,494.

To (ZZZ iii/tom it may concern:

Be it known that we, STEWART AoHnsoN and DAVID N. PLANT, citizens or the Dominion of Canada, residing at Fairfield East, @ntario, Canada, have invented new and useful improvements in Lamp-Chimney Guards, of which the following is a specification.

The purpose of the invention is to provide a device for use in conjunction with an oil burning lamp whereby the chimney may be scoured in position on the lamp after being once placed thereon. To this end, the invention comprises a wire guard attached to the chimney supporting portion of a lamp, the gzjnard being made oi wire strands and c):- tending uyfivardly and encircling the chimney, and having its ends detachably connected, so that when in connected position the danger of knocking the chimney off is :Woided. The ends of the guard may be readily separated to permit the easy removal of the chimney.

The invention is illustrated and described in a specific embodiment. to which, however, it is not to be restricted. The right is reserved to make such changes or" alterations as the actual reduction to practice may suggest in so far as such changes or alterations are compatible in spirit with the annexed claim.

In the accompanying drawings: Figure 1 is a side elevational view of a lamp chimney base with its attendant chimney, the improvec 'uard being shown used in conjunction therewith.

Fig. 2 is a section on the line of Fig. 11

Fig. 3 is a detailed perspective view showing the connection between the chimney encircling portion. of the guard and one of the upright strands, this figure also showing the 1letachably connecting ends of the chimney encircling portion.

is shown, the invention is eirployed in conjunction with the chimney bas formed usual. with. the upr' 11s 2 by means of which the cl aney o positioned. upon and held upon the base. The arms 2, however, do not insure the chimneys being retained in position in case it is subjected to a knock or jar, but the improved device which is the subject matter or" this invention does positively hold the chimney in position irrespective of shocks or jars.

The inventlon conslsts of a guard made preferably of flexible wire strands, there being three upright strands 4 which, at the lower ends are formed with eyes 5, by means of which they are suitably secured to the marginal edge of the chimney base 1. These upright strands at at their upper ends are formed with eyes 6 which provide means "for connection of the upright strands with the chimney encircling member 7. This chimney encircling member 7 constitutes a single strand of wire formed with eyes 8 at uniformlyspaced points, these eyes 8 being engaged by the eyes 7 of the upright strands Further than the eyes 8 the strand forming the chimney encircling member 7 has one end coiled and bent to provide a handle portion 9 and a hook 10 while the other end is bent and twisted to form a handle portion 11 and an eye 12, the hook 10 being engage-able with the eye 12.

The hook and eye 10 and 12 may be engaged and disengaged by grabbing the handle portions 9 and 11 between the fingers and when these members are disengaged the chimney encircling member or strand may be sprung apart to permit the removal of the chimney, but when this hook and eye are engaged the chimney encircling member embraces the chimney snugly above the point of the greatest bulge 01 the chimney, and, therefore, the latter cannot be removed from the chimney base. It thus remains locked in position on the chimney base irrespective of any shocks or jars to which it may be subjected.

The invention having been described, what is new and useful is The combination with a lamp chimney base and chimney therefor of a plurality of upright strands having their one end connected to the marginal edge of the base at uniformly spaced points there-around, and a chimney encircling member encircling the chimney above the point of greatest bulge of the latter, the remaining ends of the upri 'it strands connecting with this chimney encircling member, the latter having one end twisted and bent to form a handleand a hook therefor, the other end twisted and be t to form a handle and an eye, which latter is engaged by the hook for the useful purpose specified.

In testimony whereof we ah'ix our signatures.

STEWART ACHESON. DAVID N. PLANT.
